TOBACCO-PIPE.

i Specification of Letters Patent.

Patented Nov. 19, 1907.

f exact description of the invention, such as will enable others skilled in the art to which lit appertains to make and use the same, reference being had to the accompanyin drawingsyand to the letters and figures o reference marked thereon, which form a part of `this specification.

' This inventionrelates to improvements in tobacco pipes and possesses the new and useful features hereinafter described'and claimed.

The object of the invention is to provide `means for preventing the nicotin from entering the mouth-piece, and further means which prevent the accumulated nicotin from clogging the draft from the bowl of the pipe through to the mouthiece, all as hereinaf- *tenmore fully descri ed and specifically pointed out in the claims.

- Preceding a detail description of the 'invention, reference is made tothe accompanyindrawings, of which-'- igure 1, is an elevation of the pipe and view through the pipe bowl and stem. Fig. 3,'is a cross section on the line v-fv of Fig. 2. Fig.' 4, is a detached enlarged view of the nicotin tube. I

In' adetail description of '-.the invention, similar: referencecharacters indicate. correy sponding parts. l `The stem in its entirety constitutes three sections 1-2 and 3, the latter of'which is joined directlyT in the. bottom extension 5 of the pipe bowl, and the portion 2 is united thereto Vby a screw connection. The two portions of the stem 1 and 2 are enlarged at their ends and have a telescopic connection rovidi'iig on the interior thereof a chamber 6 which is .filled with any suitable absorbent, such as cotton; this cotton screens the air and smoke drawn therethrough and separates the nicotin therefrom. The parts are easily detached when it becomes necessary to supply the chamber with new absorbent.

The extension 5 from the pipe bowl 4 is hollow 'to provide a chamber 8 to be again'referred to, and thelower end of said extension 5 is fitted with a cap 9 in which is formed a nicotin chamber 10. Extending from the lower interior surface of the pipe bowl 4 is a nicotin tube 11 which passes through the chamber 8 and extends into the chamber 10 in the cap 9. I

The lower end of the nicotintube 11 has cut in opposite sides thereof notches 12` which extend a distance into the sides of said tube and serve 4'to revent any clogging of the lower end of tfie tube from interfering with the passage ofthe nicotin and to insure a free ypassage of the smoke. In' other words, by the provision of theseside openings 12 on eachl side of the nicotin4v tube, there is provided an avenue of escape for the nicotinladened smoke in the event the end of the tube should become clogged. It will lbe understood'that the smoke is drawn/from the bowlof the pipe through the tube 1 1, into the chamber 10 and thence upwardly' through the chamber 8' surrounding said tube and into the pipe stem where it comes in contact lWith the filtering substance in the body of the pipe stem.

We claim: y

In a tobacco pipe, a bowl having an extension with openin s of two diameters therein, the opening of ar er diameter extending from a point below t e bottom of the bowl to the extreme end of said extension and formingl a draft chamber, and the opening of less diameter extending from the bottom of the bowl to the upper end of the o ening of greater diameter, a cap united to t e end of said extension and providing an enlarged chamber below the Chamberlin the extension,

a tube projected into the o ening of less diameter in the extension/an forming a coni- `munication between the bottom of the bowl and the chamber in theca said tube having notches in its op osite si es extending from the lower end ofpthe tube upwardly a substantial distance, a ipe stem consisting of three sections, onfe o which projects into the extension from the bowl of the pipe and commnnicates with. the chamber therein which is formed by the opening of larger. diameter, vthe other section of the pipe stem being connected With said first mentioned section and In testimony whereof We afIijr our signhaving' an enlarged recess on its Aouter end, tures, in presence of two Witnesses.

and the third section of said pipe stem having u BERT F DIETER an enlarged recess, adapted to receive ab- GSTAV q sorbent majterialand to be projected into the L L recess in the end of the second-mentioned Witnesses: section of the stem, as herein shown and de- CARoLYN M. THEOBALD,
